Question:How would i go about doing this. I know that you go to y= and then put in the equation, but what about the inequality sign. Then after that you hit graph, and then my teacher said something about going to calc and then finding the minimum and then the zeros, but i dont know what that means. The shading i do manually because i have to put it on paper. So what do you do with minimum and zeros to find those intercepts.

Answers:Why do you need the zeros or intercepts? You take your y= graph and shade the upper or lower part depending on the direction of the inequality....

Question:do you know where to find a FREE calculator, in use for algebra and normal stuff... would love if there's more...
and please say it is easy to use =)

Question:Hi, I have 2 questions which have me confused slightly
1) Using graphing calculator, solve x^3-7x < -6
How would I proceed with solving this question on a graphing calculator? please explain the necessary steps
2) Solve 3x^3+x^2-8x+4>0 (Show all Algebraic Calculation)
Once again, detail would be appreciated.
***Both these questions are to be solved using a graphing Calculator***

Answers:In both cases, rewrite the inequality to have the functional form f(x) either less than or greater than zero. [ f(x) > 0 or f(x) < 0 ]
Plot the line y=f(x), then select the regions of the curve where f(x) is greater than or less than zero respectively.
[if f(x) is greater than zero, it lies above the x-axis. if f(x) is less than zero, it lies below the x-axis.]
Noting that the inequalities are strictly less than or greater than, the points on the x-axis should be represented by open circles (rather than solid dots.)
